Absolutely brilliant. On my walk this morning the clue stick struck and I realized I probably had some control over the DHCP client. Your letter was waiting for me when I sat down and saved me much wasted time.
Thanks for the help.

If you use dhclient, you can adjust the behaviour with these options in /etc/dhclient.conf. In fact, because dhclient isn't requesting any dns servers, I just get the local one set with the prepend option. supersede domain-name "localdomain"; prepend domain-name-servers 192.168.1.3; request subnet-mask, broadcast-address, time-offset, routers, domain-name, host-name; require subnet-mask; -- Stephen Patterson http://www.lexx.uklinux.net http://patter.mine.nu [EMAIL PROTECTED] remove SPAM to reply Linux Counter No: 142831 GPG Public key: 252B8B37 Last one down the pub's an MCSE -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
